3-(2'-Methylthioethyl-1'-phenyl)-4-hydroxycoumarin and 3-(2'-ethylthioethyl-1'-phenyl)-1-hydroxycoumarin were synthesized. Acetylation of these compounds with acetic anhydride and pyridine yielded respective 4-acetylcoumarins while appropriate sulfoxides and sulfones were obtained by oxidation of alkylthio substituens with H2O2. 3-(2'-ethylthioethyl-1'-phenyl)-4-hydroxycoumarin methylated with diazomethane gave 3-(2'-ethylthioethyl-1'-phenyl)-4-methoxycoumarin and 2-methoxy-3-(2'-ethylthioethyl-1'-phenyl)-chromone.
